I am Samuel Devasahayam and am a Principal Lead Program Manager for Microsoft in the Identity & Access team. I am responsible for the core components in Active Directory and lead the Active Directory Federation Services team. I have worked in Identity & Access since 1998 working on Active Directory, AD FS 2.0, Windows Identity Foundation. For Windows 8, I am building the evolution of claims-based authentication and authorization in Windows with Active Directory as a platform and working with the File Server team to light this up to provide flexible access control for files with a focus on compliance and information governance. In my free time, I love music and play the bass guitar for numerous Indian bands in the Seattle area apart from playing cricket and hiking.
